QuestionsTibia

1is the medial of the two bones in the leg2is the lateral of the two bones in the leg3is a weight-bearing bone4articulates distally with the calcaneus5has no muscles attached to its medial surface

The Tibia:

Tibia anterior aspect

1is the medial of the two bones in the legT2is the lateral of the two bones in the legF3is a weight-bearing boneT4articulates distally with the calcaneusF5has no muscles attached to its medial surfaceT

The Tibia:

Tibia anterior aspectThe tibia articulates distally with the talus, not calcaneus.The medial surface of the tibia has no muscles attached to it. The upper end of this surface receives the attachment of the pes anserinus and medial collateral ligament, but no muscles

1is called the medial tibial condyle2is called the lateral tibial condyle3gives attachment to the soleus muscle4receives the insertion of quadratus femoris 5gives attachment to the iliotibial tract

The highlighted area:

Anterior aspect of proximal right Tibia

1is called the medial tibial condyleF2is called the lateral tibial condyleT3gives attachment to the soleus muscleF4receives the insertion of quadratus femoris F5gives attachment to the iliotibial tractT

The highlighted area:

Anterior aspect of proximal right Tibia

The highlighted area is the lateral tibial condyle (anterior view). Part of this area receives the iliotibial tract. Soleus is attached to the posterior surface of the tibial shaft.

1is called the greater tuberosity2is called the ischial tuberosity3is called the tibial tuberosity4gives attachment to the patellar ligament5lies entirely within the capsule of the knee joint

The highlighted area:

Anterior aspect of proximal right Tibia

1is called the greater tuberosityF2is called the ischial tuberosityF3is called the tibial tuberosityT4gives attachment to the patellar ligamentT5lies entirely within the capsule of the knee jointF

The highlighted area:

Anterior aspect of proximal right Tibia

1is called Gerdys tubercle2is called the medial epicondyle3receives the insertion of the iliotibial tract 4is called the lateral epicondyle5gives origin to the lateral head of gastrocnemius

The highlighted area:

Anterior aspect of proximal right Tibia

1is called Gerdys tubercleT2is called the medial epicondyleF3receives the insertion of the iliotibial tract T4is called the lateral epicondyleF5gives origin to the lateral head of gastrocnemiusF

The highlighted area:

Anterior aspect of proximal right Tibia

Both heads of gastrocnemius arise from the distal femur and have no attachment whatsoever to the tibia.

1is known as the trochlear notch2is the site of attachment of the posterior cruciate ligament3is called the intercondylar eminence4gives attachment to the anterior cruciate ligament5gives attachment to the tibial collateral ligament

The highlighted area:

Posterior-Superior view of proximal right Tibia

1is known as the trochlear notchF2is the site of attachment of the posterior cruciate ligamentF3is called the intercondylar eminenceT4gives attachment to the anterior cruciate ligamentF5gives attachment to the tibial collateral ligamentF

The highlighted area:

No structures are attached to the intercondylar eminence (also known as the tibial spine).Posterior-Superior view of proximal right Tibia

1the right arrow points to the anterior intercondylar fossa2the left arrow indicates the site of attachment of the posterior cruciate3the entire upper surface is covered by articular hyaline cartilage4the posterior horn of the lateral meniscus lies in front of the posterior cruciate 5the right arrow points to the area of attachment of the anterior cruciate ligament

Concerning the upper surface of the tibia:

Posterior-Superior view of proximal right Tibia

1the right arrow points to the anterior intercondylar fossaT2the left arrow indicates the site of attachment of the posterior cruciateT3the entire upper surface is covered by articular hyaline cartilageF4the posterior horn of the lateral meniscus lies in front of the posterior cruciate T5the right arrow points to the area of attachment of the anterior cruciate ligamentT

Concerning the upper surface of the tibia:

Posterior-Superior view of proximal right Tibia

The left and right arrows indicate respectively the posterior and anterior intercondylar fossae.The intercondylar area on the tibial plateau is not covered by hyaline cartilage.

1is called the fibular notch2is called the medial malleolus3gives attachment to the medial collateral ligament4receives the insertion of tibialis anterior5articulates with the talus

The highlighted bony projection:

Anterior aspect of distal right Tibia

1is called the fibular notchF2is called the medial malleolusT3gives attachment to the medial collateral ligamentT4receives the insertion of tibialis anteriorF5articulates with the talusT

The highlighted bony projection:

Anterior aspect of distal right Tibia

While the tendon of tibialis anterior crosses the medial malleolus, its distal attachment is to the medial cuneiform and adjacent base of 1st metatarsal.

1the popliteus muscle is attached distal to the soleal line2the medial end of the soleal line is at a higher level than the lateral end3the tibial attachment of tibialis posterior is medial to that of flexor digitorum longus4no muscle fibres are attached to the distal third of the posterior surface5a vertical ridge separates the tibial attachments of tibialis posterior and flexor digitorum longus

Concerning the posterior surface of the tibia:

1the popliteus muscle is attached distal to the soleal lineF2the medial end of the soleal line is at a higher level than the lateral endF3the tibial attachment of tibialis posterior is medial to that of flexor digitorum longusF4no muscle fibres are attached to the distal third of the posterior surfaceT5a vertical ridge separates the tibial attachments of tibialis posterior and flexor digitorum longusT

Concerning the posterior surface of the tibia:

the popliteus muscle is attached proximal to the soleal line, not distal.The soleal line is an oblique ridge whose medial end is at a lower level than the lateral end.No muscle fibres are attached to any surface of the distal third of the tibial shaft.

1the posterior surface gives attachment to the medial head of gastrocnemius2the posterior surface gives attachment to flexor hallucis longus3the anterolateral surface gives attachment to tibialis anterior4popliteus is attached to the posterior surface, distal to the soleal line5the medial surface has no muscles fibres attached to it

Concerning the shaft of the tibia:

1the posterior surface gives attachment to the medial head of gastrocnemiusF2the posterior surface gives attachment to flexor hallucis longusF3the anterolateral surface gives attachment to tibialis anteriorT4popliteus is attached to the posterior surface, distal to the soleal lineF5the medial surface has no muscles fibres attached to itT

Concerning the shaft of the tibia:

Flexor hallucis longus is attached to the posterior surface of the fibula, not the tibia.

1the patellar tendon is attached to the lower half of the tibial tuberosity2the iliotibial tract is attached to the posterior aspect of the lateral tibial condyle3on the tibial plateau, the anterior horn of the lateral meniscus lies in front of the anterior horn of the medial meniscus4the medial collateral ligament of the knee is separated from the overlying tendons of sartorius, gracilis and semitendinosus by a bursa5the lateral meniscus covers a greater surface on the tibial plateau than does the medial meniscus

Concerning attachments to the proximal tibia:

The patellar tendon (also known as the patellar ligament) is attached to the upper half of the tibial tuberosity.The iliotibial tract attaches to Gerdys tubercle on the anterior aspect of the lateral tibial condyle
